i SPECIFICATION foifrning part'of Letters v:Patent No. 603,436, dated May 3, 1898. Appntuon and February 5, 1397. serai No. 622,139. (No man.)

To all whom it may concern: Y

Be it known that I, losnrnSrunns, a' citizen of the United States, and a resident of the city of Covington, in the county of Kenton and State of Kentucky, haveinvented certain new and useful Improvementsin Apparatus for Conveying Air and Vapor to Burners, of

which the following is aspeciiication.

One of the primary objects of my invention is to convey vapor generated from a gasolenef stove generator.through pipes to burners with aWelsbach or similar incandescent mantle and to provide in novel combinations means for forcing the vapor and air commingl'ed therewith upward and along the service-pipes and for preventing the vaporfrom condens-3 ing, and also convey in the vicinity of the needle-opening more air into cOmmingling-j tube to the already-generated vapor, which enables me to get a perfect combustion for a larger number of burners than could be done without it, all as hereinaftermore particularly set forth.

In the accompanying drawings, making a part of this specification, and in which similar letters of reference indicate correspond-` ing parts, Figure 1 is a side view, partly in elevation and partly in section, of mechanism embodying my invention. Fig. 2 is a view, partly in elevation andv partlyin` section, of the parts as they appear to a spectator when standing at the right of the vmechanismvof Fig. l and looking at this mechanism, the cap of the air-receiver and conductor being removed and that half of the subflame-protector which is next to the spectator being also re. moved. Fig. 3 is a vertical central section of the subflame-burner cup and of the adjacent portions of the generator and of the adjacent part of the tube for supplying the subflame-y burner with vapor. Fig. 4 is a vertical seo-V tion throughthe upper part of the generator and the needle-valve for supplying vapor to the burners and of the conduit connecting the generator with this valve and the subflame needle-valve. l

I will nowproceed my invention.

Y The primary object of my invention yis to improve-the service of gasolene-vapor in feeding the service-pipes of a system for lighting one or more rooms or apartments, o., of a to particularly describe E Y building or other structure.

Heretofore such systems of lighting by gasolene-vapor have `been to a large extent failures, and these sys- Items, though the material (gasolene) used in vaporization is much cheaper than coal-gas, have failed to successfully compete with those systems employing coal-gas. I overcome these -disadvantages heretofore incident to the imperfect systems and mechanism employed and present a successful means for utilizing gasolene-vapor by a cheap apparatus and in advantageous and thoroughly eifective operations in the lighting of houses and other structures.

I willnow proceed to describe in detail the several features of my invention and the respective modes of operation and the various advantages resulting from their use conjointly or otherwise.

A indicates a gasolene-generator, and B a delivery-pipe for supplying gasolene to the generator. l

C indicates a `needle-valve for supplying gasolene-vapor to the subflame to keep the generator hot. T hisvapor is under pressure. A simple mode ofexerting pressure upon the vapor is by elevating above the generator the tank whereby the latteris supplied with gasolene. This needle-valve C is supplied with vapor from the generatorby conduit F3. (See Fig. 4.)

D indicatesthe mixing or commingling tube for supplying the subiiame with commingled air and vapor, the vapor being that which is'- sues from valve C in the ordinary plan of a VBunsen burner.

E indicates the cup, fitting tight at the bottom jaroundthe generator-pipe A and allowing a small aperture E2 at its top all around tions in the building. This valve F-` is connected to the generator A by the conduit F3, and receiving the vapor from the generator delivers it at orifice F.

A subflame-protector G surrounds the generator `and subflame, and is suitably upheld the generator-pipe A for exit of the vapor to mantles (not herein shown) at various locavloo by eommingling-tube D at bottom and by initial heating-burner N, hereinafter mentioned.

Hindicates ahorizontal cylinder or receiver to receive air to be commingled with the gasolene-vapor coming from valve F2 and to convey it thereto under certain important conditions, as hereinfter specified. Cylinder H is preferably secured by suitable lugs or equivalent connections to the generator, preferably by being secured to t-he Iiange A2 on the upper part of the generator-pipe. The upper end of the barrel or tube of needle-valve F2 projects through the bottom of this cylinder through an opening in the latter. The edge of this opening lits close against the needle-valve tube to prevent the products of the air and gas consumed at the subflame from passing up around the needle-valve tube into the cylinder Il.

A tube K for the purpose of mixing orcommingling the air and gasolene-vapor is located in the upper part of the cylinder ll and establishes communication between the interior of the cylinder II and a point above and outside of the same. This tube K is located directly above the point of the needle-valve F2, and the axis of the tube K and of the oriee of the neeedle-valve F2 are preferably in the same vertical line. The object of this location of the tube K with reference to valve F2 is to enable the tube K to receive the vapor projected upward from the needle-valve and to transmit it upward and at the same time enable lthis moving vapor to en train with it air into mixing-tube and enable it to begin its process of eommingling, the vapor at this point being mostly in the center and the air encircling it. The commingling-tube is flared out at K2 at the lower end the better to collect the vapor from the exit-orifice of the valve F2 in case it (the vapor) should go a little to one side of the perpendicular. Vhen the needle-valve is almost closed, the vapor issuing from it is apt to leave the perpendicular, but when the needle-valve is well open the vapor ascends forcibly in a vertical line without substantial variation or deflection.

One end of the cylinder ll is provided with a removable cap H3, so as to allow of ready access to the exit-orifice F of the needle-valve F2 in case it should become clogged. The other end of the cylinder Il is provided with a grating or network or diaphragm U4, in every case having fine perforations to prevent any dust from entering cylinder H and passing up through the commingling-tube K and clogging the wire-gauze L2, located in the tube K. This same wire II4 may also be of service in preventing any flame from entering the cylinder H and igniting the vapor as it leaves the exit opening of the needlevalve F2.

On top of the cylinder ll is a collar J, connected thereto and forming a convenient support for the commingling-tube K. The pipe L is preferably supported by this same collar,

service-pipe, and thereby prevents an eXplo- 8o sion in said pipe.

Outside of and encircling the service-pipe L, I locate a gas or vapor pipe or flue M directly over the subflame of subflame-chamber E to receive the heat from the said lame. This fiue M extends upward to an extent proportionate to the distance which it is desired to force the eomminglcd air and vapor in the service-pipe, and also according to the quantity of such air and vapor to be forced up and the rate of velocity at which this commingled air and vapor are to move through the serv ice pipe or pipes. All of these functions it performs or supplements and also performs the additional function of preventing the vapor from condensing in the service-pipes. The length of the flue M will therefore vary from about two feet to twenty feet. A ilue M of less than two feet will operate within certain limits.

IOO

The hotter the air and vapor are heatedtl\`-V more air is taken in at the mixing-tube, and vice versa.

The tube II may be dispensed with and the generator may be constructed similar to the ordinary gasolene-stove generator with a suhilame, so as to prevent the products of combustion from entering the mixing-tube, and different modes may be employed for heating the air and vapor in the service-pipe leading upward with goed results.

It remains to speak of the burner N. This is located, substantially as shown in Fig. 2, so as to heat the generator A at the commencement of the operation of generating gasolenevapor for the service-pipes. This burner is fed by means of a conduct N2, connected to that main supply-pipe from the gasolene-tank which supplies the generator; but this burner may be otherwise supplied with fuel and may be by any gas instead of gasolene-vapor.

The means for heating the generator to start the generator in making vapor may be varied. For example, a drip-cup or torch, the., maybe used instead of burner N and with suitable fuel. This preliminary heating is an old process and does not enter into my invention. It is alluded to here merely to show a mechanism in all respects complete and operative.

The mode in which my invention operates is as follows: First the genc1atorA,filled with gasolene, is heated, and a vapor is generated, preferably, by a flame from the burner of nee- IIO IZO

zo'K along with the vapor.

veos-,43e 13 dle-valve N.k Then the generator-valve C for the subflame is opened, and the vapor there from, passing out at orifice E2 of the subameburner, is there lighted and continually heats the generator A, causing the latter to generate'vapor. The needle-valve F2 is now opened. The flame of the subflame-burner E serves to causethe generator to make as much vapor as is needed to escape from the two open- 1o 'ings-viz., vE2 and F. The vapor from exit- I5 heat the cylinder H by the heated air and gases from the subflame, and the heated cyl- Y inder H heatsrthe air within'it. This air, being expanded, rises, and thereby assists the needle-valve F2 in conveyin 0r air into the tube Generated vapor from valve-'orifice F issues therefrom with great force and entrains the air in the cylinder H and carries it up with it into the commingling-tube .-K but as the commingled air and z5 vapor becomes heavy when it gets cold it will form a resistance, and thereby prevent the air yfrom entering tube K as freely as it would if there were no resistance. The fresh air from cylinderorchamber H, being heated 3o and expanded, has a tendency to rise and enablesthe jet of carburetedair from generator-pipe F to more easily raise it. Inasmuch as it continues heated and expanded, it will -continueto rise after the impetus received with the generated vapor from pipe F has been exhausted, and the commingling air and vapor will continueto rise and pass along f serviceipes. Forthelatterpurpose-viz.,to

4o have devised and arranged the air and gasV supplemen the action of the cylinder H-I forcing tube M. The heat-viz., the heated -air and gases of combustion from the sublame-Will pass around the cylinder H into the space between the tube vM and pipe L,

'45 and thereby from without heat the pipe L and the air and vapor within.. This tube M may be dispensed with where there is a certain'number of burners used-say from five to nineand the vapor is not to be raised very far;

5o but when there are only a few burners used,

although the vapor does not have to be raised far, the movement of the vapor will be slow, and the air and vapor will get cold and heavy, even when the temperature is normal. There Will not be sufficient power in the current generated by the needle-valve to raise this heavy vapor.l In such cases the tube M must be employed. Another function of this supplemental pipe M is to keep gasolene-vapor 6o from condensing in the service-pipes in cold Weather, and this function is necessary in all Y cases, whether there be few or many burners and whether the mixture of vapor and air is required to beraised' a long or a short distance,

where the service-pipes run through cold places and a heavy grade of gasolene is used. This heating of the air and vapor in the servlsubstantially as described.

ice-pipe L by the hot air of pipe M prevents such condensation altogether in pipes of ordinary length. The heated air and vapor pass through the service-pipes and keep them warm and in proper condition to be conduits for the oxygenated vapor until the latter is consumed at the burners. By means of this extra apparatus of my invention I can draw more air into the service-pipes, and thus more fully oxygenize the vapor and therefore feed a larger number of burners than I could otherwise do and raise the vapor much higher and move it farther and feed burners at a higher altitude than could otherwise be done.
